After starting installer (IIRC also when selecting Live CD mode)
ReadOnlyBootPrompt crashes:

Different stack traces have been observed. In this case
BMessage::sMsgCache is NULL due to BMessage::_StaticCacheCleanup() having
been called already. The general cause seems to be that the main thread
has already called exit() while other threads are still running:
